The average price is sourced from the Office for National Statistics' House Price Index (HPI).
| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2024 6 DEC | £179,200 | £161,666 | 11% above HPI |

The below graph shows the average terraced house price in the Caerphilly local authority area over time, sourced from the HPI. The two 12 KING STREET sales from December 2011 and December 2024 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the December 2011 sale was for 22% below the HPI. So the extrapolation line tracks at 22% below the HPI over time, until the December 2024 sale, where it rises to 11% above the HPI. The line then continues to track at 11% above the HPI.

12 KING STREET might now be worth an estimated £188,489.
This is based on house price inflation of 5.2%, between December 2024 and April 2026, for terraced houses, in the Caerphilly local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 5.2% inflationary increase is applied to the most recent sale price for 12 KING STREET of £179,200 on 6th December 2024. For the value to have increased from £179,200 to £188,489 over the two years and eight months to April 2026, the following assumptions must hold true:
